GENERAL INFORMATION
1. Unless otherwise indicated, all items shown on the sketches are to be furnished and installed by the
customer.
2. Meters and current transformers will be furnished and maintained by We Energies.
3. Only meter mounting devices and service termination equipment listed in Section D of this manual are
to be used. The listing of equipment in this manual is not an endorsement or indication of suitability, but
only that it is acceptable for installation of our metering equipment and termination of our service lateral
conductors as required. It is the responsibility of the customer or their electrical contractor to verify that
the equipment is suitable for the installation and that it is installed in accordance with all applicable codes.
4. Application of these standards must be made in accordance with the Company's Electric Service Rules
and Regulations.
5. Electrical contractors are expected to acquaint themselves with the plans of other trades on the premises
being wired so that the meter can be located in accordance with the requirements set forth in this manual.
6. For all new and rewired, one or two family, single-phase residential services rated at 200 amperes or less,
We Energies will not provide an outlet location letter with a Guaranteed Available Short Circuit Current
(GASCC) or service equipment location sketch. The customer and/or the electrical contractor
will be responsible for ensuring outlet locations and service entrance facilities comply with requirements
specified in this manual and in accordance with the applicable Wisconsin or Michigan State Electrical
Codes and local ordinances. A GASCC value of 10,000 amps is to be used for these services only.
7. Accepted service entrance cable may be used where permitted by the applicable Wisconsin or Michigan
State Electrical Codes and Local Ordinances.
8. Transfer equipment used with stand-by power plants or generators shall be suitable for intended use and
be so designed and installed as to prevent the inadvertent interconnection of normal and stand-by sources
of supply in any operation of the transfer equipment. Further, transfer equipment shall be installed such
that it is located electrically on the load side of the meter. All transfer schemes shall be submitted to the
local Company office for acceptance before installation.
9. The use of approved material, tested and listed by a nationally recognized testing laboratory, and approved
methods of installation are requirements of the Wisconsin State Electrical Code by the Wisconsin State
Electrical Code Section of the Department of Commerce, and by OSHA for employers, for customer owned
electrical service equipment.
10. This manual only covers secondary services. For Primary Services refer to the Electric Service and
Metering Manual Addendum Primary Rate Requirements for Customer Substations.
NEW SERVICES
1. Before any new electric service can be installed and energized :
 The electrical contractor, building owner or general contractor must be on site to take
responsibility for the newly energized service.
 Or We Energies crews must have safe access to the service’s main disconnect.
Please Note that these requirements are in addition to requirements or contingencies such as, but not
limited to, the City OK from the Local Municipal Electrical Inspector (or Affidavit in areas where they are
used in place of the City OK), grading, permits and payment of any charges.
2. If the above conditions are not met or the service is deemed unsafe the service lateral may be installed,
but the service will not be energized. Our crew will leave a tag on site with a telephone number to call to
arrange to have the service energized after the reason(s) for not energizing the service have been
corrected.
3. If a service is energized and there is no one on site authorized to take responsibility, the main disconnect
will be left in the off position and tagged to indicate that the electric service is energized.
G-3
SECONDARY VOLTAGES
The following secondary voltages are generally available from We Energies. It must be noted that all voltages
and ampacities may not be available in all areas. There may be a charge to extend the necessary facilities to
the customer. For some classes of service, especially three phase, availability is also dependent upon the
customer’s connected load. The local office must be contacted for cost and availability of service.
• 120 Volt, 1Ø, 2-Wire ..........................................................
30 Amperes maximum
• 120/240 Volt, 1Ø, 3-Wire ................................................... 800 Amperes maximum
• 208Y/120 Volt, 3Ø, 4-Wire, grounded-wye ........................ 4000 Amperes maximum
• 480Y/277 Volt, 3Ø, 4-Wire, grounded-wye ........................ 4000 Amperes maximum
• 208Y/120 Volt, 1Ø, 3-Wire Service .................................... 100 Amperes/Position maximum
(limited availability)
• 2400 Volt, 3Ø, 3-Wire Service ........................................... 800 kW load maximum
(generally used for municipal wells, contact
local office for requirements)
Secondary voltages no longer provided as new services:
• 240 Volt, 3Ø, 3-Wire Service, Grounded B Phase
• 480 Volt, 3Ø, 3-Wire Service
For services greater than 2000 Amperes and for services using 100% rated Breakers, the Percent Load Factor
needs to be calculated as follows:
% Load Factor 
Average Load of Daily Cycle
x 100
Daily Maximum 1 Hour Average
Where: The “Average Load of Daily Cycle” is equal to the sum of the average hourly current (in amperes) in a
24 hour period divided by 24.
The “Daily Maximum 1 Hour Average” is equal to the highest average hourly current (in amperes).
Once the % Load Factor has been determined, provide the % Load Factor with your service application.

GENERAL REQUIREMENTS FOR METERING
General
The information covered in this section is applicable to overhead, underground, substation, and AC network
sources of supply covered in the foregoing sections of the manual.
Location of Meters and Metering Equipment
1. Outdoor metering is required for residential, one or two customer, and farm installations with 1-phase service
of 200 amperes or less.
2. Meters shall be installed outdoors in cases such as summer dwellings and other premises not occupied during
the entire year or not accessible during regular working hours of Company personnel.
3. For outdoor installations with an OH service drop, the centerline of all meters shall be between 4 and 6 feet
from the finished grade.
4. For outdoor installations with an UG service lateral, the centerline of all meters shall be between 3 and 6 feet
from the finished grade.
5. For indoor installations, locate meters in the basement or other suitable and readily accessible place as near
as possible to the point where the service enters the building. The centerline of all meters shall be between 4
and 6 feet above the floor (not applicable to ganged or grouped installations of more than 2 units as covered
in 6 below).
6. For indoor group installations the centerline of all meters shall be between 2 and 6 feet above the floor. For
apartment, commercial and other appropriate buildings of more than 2 floors, meters may be located on the
different floors of the building provided they are grouped in enclosures as near as practicable to the risers
serving the floors and the wiring and metering layout for the building is accepted by the Company.
7. For multiple unit buildings (two or more), each meter position shall be marked on the outside of the socket or
by the breaker (if available) with the address of the unit served. If the marking is on outside of the removable
cover, it shall also be marked on the inside of the meter socket in a visible location. This marking shall also
be placed on the corresponding distribution panel(s). The marking shall be a permanent label with 1/2" block
letters and may consist of individual self-stick letters or numbers, suitable for the location so as to be
considered permanent.
8. There shall be a 3' minimum of unobstructed working space, measured from the meter face, in front of all
meters. This space shall extend from the floor or grade to a height of 6'-6". At least one entrance of sufficient
area shall be provided to give access to this working space.
9. The unobstructed space required in front of meter cabinets, current transformer compartments, and
transformer loss compensation cabinets shall be as defined by the "Working Space About Electrical
Equipment" section 110.26 of the National Electrical Code (latest revision as adopted by the states
of Michigan and Wisconsin). This unobstructed space shall extend from the floor or ground to a height
of 6'-6". Equipment doors are required by the NEC to open a minimum of 90°.
10. Ample space shall be provided for all meters, metering equipment, and other apparatus so that they can
be safely read, inspected, and tested. Meter equipment shall not be located:
a. In animal enclosures, attics, closets, elevator or ventilating shafts, hallways, living quarters, stairways,
or rooms containing corrosive or explosive vapors (battery rooms).
b. Near stoves, radiators, steam or hot water pipes, or within 5' of moving machinery.
c. Above laundry equipment, plumbing fixtures or other bulky equipment.
d. Behind shrubbery or swinging doors, or over alleys, driveways, decks or porches (or over sidewalks
where practicable), or where it is necessary to trespass on adjacent property.
e. In hazardous locations as defined in articles 500 to 516 of the National Electric Code as amended
in Michigan by the Michigan Administrative Code and as amended in Wisconsin by the Wisconsin
Administrative Code.
f. Where subject to damage from falling ice, snow or other debris. If the metering equipment cannot be
moved to an area free of these hazards the necessary protection may be provided by a roof overhang or
gutter that extends a minimum of 12" past the face of the meter socket. In place of the roof overhang the
customer shall provide and install a deflector that shall extend 12" past the face of the meter socket and
be installed at a height greater than 6'-6" to comply with Notes 8 & 9 above.
11. Meter locations shall be free from excessive moisture, vibrations, and heat. Meters shall not be placed on
partitions, insecure walls or over doorways. Meters shall be shielded from magnetic disturbances and
protected from mechanical damage, moving machinery and belts by means of a suitable protecting cabinet.
12. 3' horizontal clearance between gas and electric metering equipment should be provided.
M-2
Methods of Mounting Metering Equipment
1. Socket-type meter mounting devices installed on concrete or masonry walls shall be fastened by
non-corrosive metal machine screws in lead sleeve, wedge-type expansion anchors.
2. All mounting devices for metering equipment shall be plumb.
Methods of Wiring Service Equipment and Meters
1. On outdoor installations, the knockouts of meter sockets, transockets, or meter pedestals shall not be used for
service entrance conductors unless the knockouts are located entirely below the lowest live parts.
2. Metered and unmetered conductors shall not be installed in the same conduit, wiring trough, channel, gutter
or similar enclosure.
3. Where a group of meters is supplied from a service raceway, the covers of the raceway must be provided with
a means for sealing where individual service taps are made into the raceway.
4. Termination compartments, meter mounting devices or current transformer compartments shall not be used
as junction boxes for additional customer circuit connections.
a. This includes taps for emergency circuits or fire alarms.
b. At single metered installations where 2 to 6 disconnects are used in place of a single main disconnect, a
customer owned junction box or switchboard section shall be installed on the load side of all Company
facilities for the purpose of making taps to the individual disconnects.
c. Customer provided termination compartments and transockets are permitted to have up to 2 circuits exiting
them.
5. Sockets shall be equipped with blank covers furnished by the customer at the time of installation.
6. The rating of a single service switch or the combined rating of all service switches connected to a
1-phase 120/240 volt service shall not exceed 400 amperes unless accepted by the Company.
7. A common grounding conductor shall be used to ground the service entrance equipment and the grounded
circuit conductor. A grounding conductor shall not be run from the meter socket to ground or through the
meter socket, termination compartment or transocket in going from the customer's main service switch or
disconnect means to ground. Direct grounding of meter sockets is permissible, only on meter poles where
the disconnecting means is installed at some other location. For multi-metered installations the grounding
electrode conductor may be bonded to the neutral in a termination compartment.
8. Service switches or service breakers shall be installed so that any one service switch or breaker, when
disconnected, shall not interrupt continuity of service to any other separately metered customer on the
premises.
9. All large installations not covered by this Metering Section require special consideration and the Company
shall be consulted in all cases. The customer shall submit 3 drawings of the proposed service equipment
and metering arrangement to the local Company office for acceptance.
10. Any service entrance that serves a 24-hour load, 30 days each month of 150 amperes or more, shall have
a current transformer metering installation.
11. Any fire pump service where the Full Load Running Amperage (FLRA) of the pump(s) exceeds 125 Amperes
shall have a current transformer metering installation.
12. On outdoor current transformer installations the meter cabinet and conduit shall be grounded, either by
bonding to the service entrance conduit or bus duct.
13. The Company shall meter only those voltages supplied to the customer by the Company; there will be no
Company metering after a customer-owned stepdown transformer.
14. On new installations it is the customer’s responsibility to ensure that the meter stops or grounding brackets
are clean and provide for a good electrical contact with the meter base.
15. Multi-metered installations shall be installed so as to balance the load on the service.
